Near-surface atoms from a Cu(001) surface were imaged using 3p photo- electron holograms. The angle-dependent electron diffraction patterns that constitute an electron hologram were Fourier transformed to create a tree dimensional, real-space image of the scattering atoms. We have made use of a multiple-wavenumber, phased summing method to improve the atom imaging capabilities of exerimental photoelectron holography using the Cu(001) proto-type system.
